Question

valentino’s pizzeria sells four types of pizza crust. last week, the owner tracked the number sold of each type, and this is what she found.
type of crust | number sold
thin crust | 292
thick crust | 236
stuffed crust | 158
pan style | 190
based on this information, of the next 4500 pizzas she sells, how many should she expect to be thick crust or pan style? round your answer to the nearest whole number. do not round any intermediate calculations.

Explanation:

Step1: Calculate total sold last week

First, find the total number of pizzas sold last week by adding the number sold for each crust type.
Total = 292 + 236 + 158 + 190 = 876

Step2: Calculate number of thick or pan style

Next, find the number of thick crust and pan style pizzas sold last week: 236 + 190 = 426

Step3: Find the probability

Then, calculate the probability of a pizza being thick crust or pan style: $\frac{426}{876}$

Step4: Predict for 4500 pizzas

Finally, multiply this probability by 4500 to find the expected number: $4500\times\frac{426}{876}$
Calculate this: $4500\times\frac{426}{876} = \frac{4500\times426}{876} = \frac{1917000}{876} \approx 2188.356$
Round to the nearest whole number.

Answer:

2188
